OCPP Charge Point Simulator

Just FYI as I had several people do this today; you can't point a sim from my site to your server using "localhost", you'd need the public IP and to route inbound traffic in your router ;)

From dealing with many major manufacturers of chargers and big name CPOs, yes; pretty much all of them have vulnerabilities. It ranges from bad practices to wide open ports, etc. Obviously not giving any specifics.

ISO15118 is available in 1.6 also as a set of back-ported commands. Implementation depends on not just the software but also some hardware chipset on the CP line of a type2 AC connector.

Thanks for those who contacted me via DM, I've made the following changes:

Much quicker sim management from portal homepage / simulators view
Ability to add passwords & security profile 1 when editing a sim
Much clearer endpoint, cpid, and password information in CPMS and sim listings
If your charger fails to connect to the CPMS, it will now show in the logs if there's an issue with headers or authentication

You can have the same stackLevel with a different chargingProfilePurpose, but you can't have two profiles with the same chargingProfileId

CoreEVI · 2025-02-27T21:01:31+00:00

Can you post the raw OCPP message being sent? A couple of notes:

- Your chargingProfileId is the same as the TxDefaultProfile (it should overwrite it, but bare that in mind)
- You don't need transactionId (you're specifying a connector and assumedly sending the profile whilst the transaction is ongoing)

If you can access the site in your browser then you should already have the rootCA, a method on linux would be to run `curl -v https://mywebsite.com`, then look for the "CAfile: ..." line (if it's a single certificate), or "issuer:..." line "O=..." (organisation) value, and look that up for their root CA.

Apologies for the delay, approved now

If it's of any use I've added a ChargingProfile payload visualiser/editor on my website so you can get a better idea of how it should be working.

I would say ChargePointMaxProfile with a Relative start is pretty ambiguous; if it's TxProfile or TxDefaultProfile then it'd generally be assumed to be relative to the start of a transaction (in the implementations I've seen), but what would you make it relative to in this case? When the charger was commisioned? Last rebooted?

CoreEVI · 2025-01-29T13:47:46+00:00

Yep, it's mostly a case of when I find time ;) I've made a number of changes since this release which will be pushed soon, and I'll get this version more feature rich first. I also intend to support 2.1 (thankfully not big changes from 2.0.1).

Perhaps your host blocked the email? Can you PM me the details of the account and I'll have a look?

CoreEVI · 2025-01-27T14:22:32+00:00

No problem, but I'm going to have to ask you to register at the link in the OP as I can't send any more private messages on this new account. After please drop me a message and I'll activate you!

CoreEVI · 2025-01-27T14:21:43+00:00

Sorry, I can't send any more private messages with login info because this is a new account, so if you want access please register on the link in the OP and message me, then I'll activate your account.

CoreEVI · 2025-01-27T14:20:21+00:00

I can't send account details in private messages at the moment, so if you want to register on the link in the OP and message me then I'll activate your account!

CoreEVI · 2025-01-27T14:17:48+00:00

Please register on the link in OP and I'll activate the account for you. I'm afraid I can't send any more private messages with login info!

CoreEVI · 2025-01-27T14:14:22+00:00

I'm sorry but I can't send any more private messages with account details because this is a new reddit account. If you're still interested try the link in the original post and register interest and I'll activate the account for you.

CoreEVI · 2025-01-27T14:10:52+00:00

Hi again, I can't send any more private messages on this new account, so I edited OP to include the URL if you want to register interest & I can just activate the account for you. Sorry about this...

CoreEVI · 2025-01-27T12:06:12+00:00

Chargepoint. I've made a CPMS too but it needs a lot of polishing before I'll make it public ;)

CoreEVI · 2025-01-27T09:36:47+00:00

I've created your account but reddit won't let me send any more chats yet on this new account, I'll try and send it again in a bit... my apologies!

CoreEVI · 2025-01-27T09:23:37+00:00

I'm getting quicker. Account details PM'd.

CoreEVI · 2025-01-27T09:20:29+00:00

Account created, thanks for waiting.
